How calcined bauxite is made matters more than its alumina content. Small variations in raw ore, particle size, temperature control, and cooling can lead to unstable density, inconsistent porosity, and shorter refractory life. That’s why SEPPE uses rotary kiln processing – for consistent temperature control, batch stability, and reliable performance in refractory and abrasive applications. Need stable calcined bauxite?

Due to their unique combination of low density, high strength, and thermal resistance, SEPPE cenospheres are replacing traditional fillers across multiple industries. Below are four proven applications where cenosphere fillers deliver measurable benefits. 

Cenospheres are one of the most versatile industrial fillers available today. But what exactly are they, and why should you choose SEPPE cenospheres for your applications? What Is a Cenosphere?

Calcined bauxite is a key raw material in refractory production. After high-temperature calcination (1100°C to 1600°C), Al₂O₃ content increases from 57%-58% in raw bauxite to 70%-88%. This makes it the structural backbone of refractory castables, firebricks, and other high-temperature materials. How

Dense Corundum, also known as Dense Fused Alumina (DFA), is a premium-grade fused aluminum oxide produced by melting high-purity alumina (Al₂O₃ ≥ 99%) in an electric arc furnace at temperatures above 2000°C. Through controlled cooling and precise crushing, it forms a high-density, low-porosity crystalline material with exceptional hardness and stability.

Color: Pure white. It can be widely used in products with requirements for appearance color.Light weight and large volume: The density of hollow glass microspheres is about one tenth of that of traditional filler particles. After filling, it can greatly reduce the basis weight of the product, replac
